Hello,
I add an ElementChangedListener to the JavaCore class and get notified
for every java changes. Also I wrote a wizard that creates a bunch of
methods at once, but since I added the Listener I get notified for every
method the wizard adds instead of one notification when the wizard is done.
Any idea what I making wrong?
I thought that it is enough to get a working copy of the type that the
wizard will manipulate or do I make something wrong?
IEditorInput input= editorPart.getEditorInput();
IWorkingCopyManager manager= JavaUI.getWorkingCopyManager();
try {
manager.connect(input);
try {
ICompilationUnit workingCopy = manager.getWorkingCopy(input);
IType[] types = workingCopy.getAllTypes();
if (types.length>0) {
StandardEventMethodsWizard.openDialog(types[0]);
}
} finally {
manager.disconnect(input);
}
} catch (CoreException e) {
DMSPlugin.log(e);
}
Thanks for any help.
Ingo

Fine, now it is running as a atmic operation. But do I still need a
working copy?
Thx
